Ok, I lost a day-and-a-half this week due to a disk that decided to get 
read errors due to an unfortunate power outage, and had to spend too much 
time regenerating my normal setup, but I don't think I lost any emails, 
and things seemed to have calmed down a bit, so here's to hoping that -rc6 
is starting to look better.

The dirstat shows the usual pattern of most changes being in drivers and 
architecture updates, although this time it's a bit skewed by the parisc 
and powerpc updates (hopefully closing the parisc compile regression among 
other things), which means that arch is about half, and drivers are just 
under a third of the patch (it seems to be usually the other way around). 

Documentation updates bring most of the rest:

	   5.4% Documentation/laptops/
	   2.7% Documentation/power/
	  17.0% Documentation/
	   3.8% arch/arm/
	   9.1% arch/mips/
	   8.1% arch/parisc/configs/
	  16.8% arch/parisc/
	  13.7% arch/powerpc/configs/
	  15.6% arch/powerpc/
	  46.4% arch/
	   2.3% drivers/ata/
	   8.7% drivers/memstick/host/
	   9.5% drivers/memstick/
	   4.2% drivers/video/
	  27.4% drivers/
	   2.2% fs/
	   2.3% include/

but the above is hiding the fact that there's a lot of small updates all 
over that just aren't big enough to show up in the percentage counts, but 
hopefully help drive down the regression list. More still pending, though.

Shortlog appended, patches and git trees in all the usual places once they 
have mirrored out.

That commit broke lmsensros here ( found by bisect ).

Can't access procfs/sysfs file
Kernel interface access error
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!

...

Of course proc and sysfs is mounted and the lib has that support :)

This has been reported as:
http://bugzilla.kernel.org/show_bug.cgi?id=10259
https://bugzilla.redhat.com/show_bug.cgi?id=437637

The generic thermal zone device does something which is not
fundamentally incorrect but that libsensors doesn't expect, and
unfortunately libsensors was not made robust enough and dies instead of
just ignoring the new unexpected device. libsensors 2.10.x is already
fixed in lm-sensors' SVN [1] and a tentative patch is available for
libsensors 3.0.x [2], however I am worried that kernel 2.6.25 will be
released before any new version of lm-sensors so pretty much every user
of lm-sensors will hit the problem if they upgrade to the new kernel.
For this reason, I think we really should let the new generic thermal
zone driver build as a module, and make it's hwmon support optional and
disabled by default for 2.6.25 [3]. This will help mitigate the risk of
massive breakage and complaints.

Hmm , ok but then the situation is even worse.

Why something *known* to break _all_ existing lmsensors setups out there 
is being pushed that late in game ? 

IMO that should be just reverted from 2.6.25 and pushed again in the next merge window.

Best Regards,

Gabriel

I completely agree that it shouldn't have been included that late in
the release cycle, in particular when it obviously received no testing
at all (it breaks all versions of lm-sensors.)

The reason why it was merged is that some people feared that
application authors would add support for the new thermal zone
interface (/sys/class/thermal) quickly instead of waiting for the same
information to be exported through the standard hwmon interface
(/sys/class/hwmon) which libsensors supports. This now appears to be a
very small problem compared to breaking lm-sensors for all users out
there.

This would be totally fine with me, yes.

I'll disable it in 2.6.25 and we can hopefully get it right in 2.6.26.
